Uh, didn't we fix this a long time ago? Client-Supplied GUIDs are evil :(
This has come up at some point, and as far as I recall, we dropped the requirement to provide the GUID. So I suspect one can provide a claim without a GUID, else something went wrong somewhere.
I have filed https://bugzilla.wikimedia.org/show_bug.cgi?id=61950 now.
